In winter of a country, it rains 45% of the days and shine 55% of the days. Mr. X has a barometer which wrongly predicts 5% of the time in rainy days and 10% on shiny days. Mr. X does not carry umbrella if barometer predicts shine. On good shiny morning in winter, his barometer predicts “shine” and he does not carry umbrella. What is the probability that Mr. X will suffer from rain on that day.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
In winter of a country, it rains 45% of the days and shine 55% of the days. Mr. X has a
barometer which wrongly predicts 5% of the time in rainy days and 10% on shiny days.
Mr. X does not carry umbrella if barometer predicts shine. On good shiny morning in
winter, his barometer predicts “shine” and he does not carry umbrella. What is the
probability that Mr. X will suffer from rain on that day.
